The ring holder is called a circlip groove or just simply a groove,

Circlip pliers are often mentioned but the clip isnt a circlip and crclip pliers will rarely work or at least they are the incorrect tool for doing it,
The clip is a clip, its not a circlip, its an open ended steel clip, they are not sprung like circlips and they dont have the eyes in the ends for circlip pliers,
You didnt mention holes nor springiness and just a gap in a clip so im assumeing its the same as the ones you find in euro locks,
The way to remove them is to pry out one end until it slides off the lock, a screw driver is a favoured tool finished off with some long nose pliers but basically use anything you have that will fit in the gap and force it out then work the clip out,
To put back simply squeeze it back together with your long nose pliers and finsih off with a screw driver if needbe, be careful it doesnt rub on the casement,
If it is indeed a clip with an eye on each end then its a circlip and sprung, two screwdrivers could work at a push but circlip pliers are the correct tool and method of doing it,
